I suspect the interpretation of -d '' to mean a NUL byte delimiter may have been an accident originally (but that's a guess). But it's an incredibly useful feature, and has been used in countless real life scripts. At this point, while it is still undocumented, it is nevertheless a feature whose omission would be considered a regression. Others have correctly described the difference between -d'' and -d '' so I won't repeat that, except to say that they are right.
